With an orbital period of nearly two millennia long, the cold and distant Vioresa was actually missed in the initial asari survey of the system. Only a follow-up mineral assay sent to Canalus by a volus mining concern noticed its subtle movement across the stars.
Vioresa is a methane-ammonia ice giant, circled by a retinue of deep-frozen moons. Its remoteness makes it a popular drive discharge point for pirates working the Pylos Nebula cluster. In the last two years, several dozen ships have disappeared while passing through the Dirada system. As Pylos is currently unclaimed by any sovereign power, Council naval patrols and few and far between. Thus far none of the pirates responsible have been apprehended.
